Research Interests

Ontological reasoning, context-aware computing, pervasive personalisation, scrutable personalisation, mobile personalisation.

About

In 2003 William completed his bachelor degree in Computer Science with First-class Honours from the University of Waikato in New Zealand. In 2004, he started a PhD under Professor Judy Kay's supervision with a university/faculty scholarship (UPA-cofunded), and later on he also received a top-up scholarship from the Smart Internet Technology Cooperative Research Centre. He completed his PhD in 2008.

William's thesis is "Ontological Reasoning about Location for Indoor Pervasive Computing Environments". The objective is to build a flexible framework for ontological reasoning in the pervasive computing environment. The thesis exploits three aspects of pervasive computing with this framework: location conflict resolution, personalisation, and system explanation.

Current Projects
